Priors used for each parameter, unless stated otherwise in the text.

Parameter Units Prior distribution Description
Offsets and noise
Epoch BJD Fixed at 2455 500 Reference epoch
γinst m s−1 U [RVmin, RVmax] Constant velocity offset
σRV m s−1 log U [0.001, 100] Additional white noise (Jitter)
PGP days U [1, obs timespan] Period of correlated noise
ρGP days U [1, obs timespan] Decay timescale
ηGP U [0, 100] Smoothing parameter
σGP m s−1 U [0, 100] Amplitude of correlated noise
Keplerians
P days U [1.5, 5000] Orbital period
K m s−1 log U [0.1, 105] RV semi-amplitude
e U [0, 0.8] Orbital eccentricity
ω Radians U [0, 2π] Argument of periastron
λ0 Radians U [0, 2π] Mean longitude at epoch

Notes. RVmin and RVmax are the minimum and maximum measured RV, respectively, for each star. U denotes a Uniform prior and log U denotes a logarithmic Uniform prior.
